PSU Wattage?

**Dave Hybrid** · #1 3rd Mar 2008, 05:47 AM

Ok so I'm going to get a new PSU as my machine has a strange hanging issue and I'm 99% the PSU is causing it.

I just have no idea what wattage I need, my PC spec is in my sig.

Cheers guys!

I would go with anything above 600w, but make sure it is from a good name brand, like Enermax or BFG

Who do you work out what wattage you need social?

I just judge by looking at it really, No real system just what I think it should be!

go for higher than you need then you can upgrade effortlessly

open your tower case and check the psu it should say in the side what wattage it is then go with the nearest 100+ for exaple say your psu is at 350 watts go for a 450 watt or morebut more isnt always better depending on what you use your computer for anything above 600 watt isnt really needed unless your into modding and stuff hope this helps

Hey up Dave.

An e6750 at stock needs around 65w, a 8600GT needs, depending on factory oc, around 45w.

But as you're oc'ing both and taking into account your other components I'd be looking at a decent 500w.

Anything above is overkill.

But also taking into account upgrading i'd be looking for a 600w.

Sorry, just poking fun.

Picking a number then adding another 100 isn't the best of advice.

PSU wattage is generally governed by the hardware you are running so I was looking for something more concrete based on my PC spec.
